There is more than one way to add a back-up camera to the Slingshot. This is just the way that I did and it has been working flawlessly for 6 months now.

I pulled 12v ignition power for the camera from the main harness behind the dash. As I was already running an RCA for the camera it was an easy spot to get power when wiring up the Stereo harness.
